As any dog owner will tell you, your pet's first year flies by in a flash. So much so, that new owners often don't realise just how much their companion has grown.
Astonishing growth
On TikTok, the owner behind the account “Thunderpup_!” shared the first year of her Saint Bernard puppy's life.
In just a few months, the big pup went from a few pounds to nearly 7 stone (approx. 99 pounds) by the time he was 6 months old.
A viral sensation
The video shared by his owners delighted viewers, who were amazed to see the adorable puppy's transformation. It's an incredible change!
It's worth remembering that a male Saint Bernard can weigh over 14 stone (approx. 198 pounds) as an adult.
